The Saddest Story I Know

While at a convention, Bill, Jim, and Scott shared a hotel suite on the 75th floor. After a long day of meetings, they were shocked to find that the hotel elevators were broken and that they’d have to climb all the way up to their room.
“I have a way to break the monotony,” said Bill. “I’ll tell jokes for 25 flights, Jim can sing songs for the next 25, and Scott can tell sad stories the rest of the way.”
As they started walking up, Bill told his first joke. At the 26th floor, Jim began to sing. At the 51st floor, it was Scott’s turn.
“I will tell my saddest story first,” he said. “Once there was a man who left the room key in the car.”
